Subject: [PATCH 23/30] join: add all attributes while creating computer object
It is possible to create special accounts which can only join a computer
to a domain but is not allowed to do any further operations which the
computer object. As a result if such an account is used during the join
only the ldapadd operation is permitted but not any later ldapmodify
operation. To create the computer object correctly in this case all
attributes must be added while the object is created and not later.
